Abstract

We studied the features of the appearance of broadband “white” emission in CaF2-x mol% ErF3 and ZrO2-x mol% Er2O3 (x = 0–25) nanosized dielectric particles upon their excitation by intense laser radiation with λexc = 1550 nm. Comparison of the results of this study with the results obtained previously for other materials doped with Er3+ ions confirmed the thermal nature of the observed emission and made it possible to identify the main factors affecting its occurrence. These include the band gap of the material and the presence of defects in its structure. A method of applying the effect in dermatology is proposed.
